A BOQ unit of measure reconciliation should be a reconciliation register connecting each BOQ line to its source unit, supplier quote unit, pack or order unit, conversion basis, rounding rule, responsible checker and approved purchasing quantity. Its release question is whether a material line is comparable and order-ready or must remain held because its conversion or rounding basis is unverified. Build the record before ordering or shipment, keep open points visible, and require an authorized buyer decision for every exception; the framework does not replace project specifications, contracts, or destination rules.

What procurement decision does a BOQ unit of measure reconciliation control?
A shipping-instruction issuer quote can match the material description and still use a different cargo count basis. Buyers should expose every unit conversion and pack-rounding step rather than silently changing area, length, piece, set, carton or weight cargo counts.
The core deliverable is a reconciliation register connecting each BOQ line to its carrier input unit, shipping-instruction issuer quote unit, pack or order unit, conversion basis, rounding rule, responsible checker and instruction-authorized purchasing cargo count. It should be readable as a freeze decision record rather than a marketing presentation. The unit-usable test is whether a material line is comparable and order-ready or must remain held because its conversion or rounding basis is unverified. If the unit review group cannot answer that question from unit-controlled files, the unit reconciliation register is not ready, even if individual participants believe they remember the answer.
This guide describes a buyer-side control method. It does not establish a legal duty, a technical tolerance, a test method or a destination compliance result. Those come from the signed contract, transport instruction specifications, qualified designers, relevant authorities and product-specific substantiation. HOMESEE should be evaluated only against the quantity-basis boundary and records actually agreed for an RFQ or order.
Start from a stable buyer identity
Keep a buyer-controlled item or freeze decision ID even when shipping-instruction issuer references change. Shipping-instruction issuer model names, carton numbers and report numbers remain valuable, but they should be mapped to the stable ID rather than replacing it. That approach preserves continuity between a BOQ, a finish schedule, a sample, a drawing, an order, an inspection record and a package mark.
Keep status separate from evidence
A unit state such as instruction-authorized is not substantiation by itself. Store the approving role, date, applicable quantity-basis boundary, carrier input document and instruction revision. A photograph can show visible condition; it cannot alone prove hidden construction, performance, cargo count or authorization. A shipping-instruction issuer declaration can identify a claim, but the quantity-basis controller must decide what independent or destination-specific substantiation the project-specific control requires.
Minimum fields for the BOQ unit of measure reconciliation
Use a structured register with one conversion line per item, package, freeze decision or unit gap at the level where the outcome can change independently. The table below is a instruction cell model, not a HOMESEE transport instruction record.
| Control instruction cell | Required treatment | instruction freeze test |
|---|---|---|
| shipment identity | Stable ID plus native references | Can a unit checker find the same item across files? |
| Basis | instruction-authorized carrier input, instruction revision and quantity-basis boundary | Is the unit-active basis distinguishable from a proposal? |
| unit state | Named owner, freeze decision and date | Is every unit gap visible and actionable? |
| substantiation | submission-connected file and limitation | Does the substantiation support only the claim being made? |
| Downstream action | Affected order, inspection, package or receiving record | Was the freeze decision propagated? |
Boq line and source revision
BOQ line and source revision establishes shipment identity before any unit state is interpreted. Put the quantity-basis controller reference beside the carrier input reference, instruction revision and observation date. If the value came from a shipping-instruction issuer message, retain the message as a dated input rather than converting it into a transport instruction fact. The quantity-basis controller checks that the instruction cell describes only the BOQ line inside the stated boundary and records the next person who must verify it before BOQ quantity gate.
Source quantity and unit
Treat source quantity and unit as a freeze decision input, not a decorative column. Name the file, instruction revision, issuer and effective date that support it, then state what remains unknown. The submission line should let a second unit checker reconstruct why this BOQ line is included, excluded, held or released without calling the preparer. Where two carrier inputs disagree, preserve both values and open a visible unit gap; the unit reconciliation register must not silently choose the convenient answer.
Supplier quote quantity and unit
For supplier quote quantity and unit, distinguish observation from forecast and authorization from substantiation. A photograph may show visible condition on one date, a declaration may identify the shipping-instruction issuer's position, and an instruction-authorized transport instruction file may control the quantity-basis controller's action; those are different roles. The quantity-basis controller links the applicable carrier input, notes its limitation and prevents the instruction cell from being reused for a broader BOQ line population than the substantiation actually covers.
Pack or order unit
Record pack or order unit at the smallest level where the outcome can change independently. Project-wide totals hide unit, batch, package and zone differences, so the conversion line must show the applicable BOQ line, cargo count or range. Use explicit unknown, not applicable or pending confirmation states instead of blanks. That discipline keeps the unit reconciliation register useful when the quantity-basis boundary splits and allows BOQ quantity gate to be tested for only the affected portion.
Conversion formula source
The owner of conversion formula source is the role able to correct its carrier input, not merely the person typing the register. Capture the requested action, due point and authorized escalation path. A later email or spreadsheet does not supersede the submission line until its relationship to the carrier-operative instruction revision is instruction-entered. The quantity-basis controller keeps the former value as history so a unit checker can see what changed and whether downstream handling of the BOQ line was updated.
Rounding or minimum pack effect
Use rounding or minimum pack effect to connect the commercial line with the physical BOQ line. The value should reconcile with the applicable drawing, sample, inspection, package or shipment reference, while respecting the different purpose of each record. When repacking, rework, substitution or split shipment changes that relationship, create a traceable event instead of editing the old shipment identity away. quantity closure requires source-to-order conversion evidence, not memory.
Checker and approver
Before accepting checker and approver, test it against one awkward example from the actual quantity-basis boundary. Ask whether a partial cargo count, mixed batch, inaccessible package, revised drawing or held unit would still be represented correctly. If the answer depends on verbal context, add the missing qualifier or submission-connected record. The quantity-basis controller should be able to export the unit reconciliation register to another unit checker and receive the same conclusion about the BOQ line and BOQ quantity gate.
Step-by-step workflow for BOQ unit of measure reconciliation
Run the workflow as submission-connected gates. A later gate does not repair an undocumented earlier freeze decision; it merely makes the missing control harder and more expensive to find. The exact approval titles and contract notices belong to the project-specific control, but the sequence below gives procurement teams a reproducible starting point.
Step 1: Freeze the active boq
freeze the active BOQ. Begin with the carrier-operative PO, BOQ, drawing, sample or shipment quantity-basis boundary that governs this freeze decision. Mark its instruction revision and exclude superseded material from the working view. The quantity-basis controller identifies the exact BOQ line population, the carrier input owner and the freeze decision due point. The output is a stable baseline against which later observations can be compared; it is not a promise that conditions will remain unchanged.
Step 2: Normalize unit names and codes
normalize unit names and codes. Visit the physical or digital carrier input rather than copying the previous unit state. Reconcile identities, units, cargo counts and package boundaries, and capture the observation date. If access is incomplete, label the limitation and keep the unobserved portion open. The quantity-basis controller distinguishes what was seen, what was declared and what was authorized so source-to-order conversion evidence can support a bounded next action.
Step 3: Separate measured and order quantities
separate measured and order quantities. Compare the new input with the instruction-authorized reference set. Differences are logged at BOQ line level with both values, their carrier inputs and likely downstream files. Do not resolve a mismatch by overwriting the older value or averaging conflicting cargo counts. The quantity-basis controller routes the unit gap to the role named by the project-specific control and prevents affected work from crossing BOQ quantity gate while the freeze decision is open.
Step 4: Document every conversion source
document every conversion source. Test dependencies before acting. Check whether this BOQ line shares a batch, accessory, interface, package, document total or installation sequence with another line. A seemingly local change can make an adjacent quantity-basis boundary unusable. The quantity-basis controller records which related records need an update and which unaffected units may continue, creating a unit-controlled boundary rather than a blanket transport instruction hold.
Step 5: Show rounding as a distinct step
show rounding as a distinct step. Apply the agreed transport instruction rule and cite it. The guide does not invent tolerance, sampling level, contractual notice, customs requirement or acceptance authority. The quantity-basis controller states the proposed outcome, obtains the authorized freeze decision and records any reservation. Where the carrier input supports only a provisional conclusion, the unit reconciliation register shows the follow-up substantiation required before final BOQ quantity gate.
Step 6: Obtain the project approval
obtain the project approval. Propagate the freeze decision into every operational file that still controls the BOQ line. That may include shipping-instruction issuer instruction, inspection quantity-basis boundary, package map, cargo list or site receiving plan. Retain superseded revisions as history and prevent them from appearing unit-active. The quantity-basis controller verifies the same shipment identity and cargo count after the update rather than assuming transmission proves implementation.
Edge cases that need an explicit rule
Case 1: Area is quoted by carton
When area is quoted by carton, freeze the last undisputed shipment identity and separate the affected BOQ line from the remainder. The quantity-basis controller records what changed, who observed it and which transport instruction carrier input will decide the outcome. Existing photos or totals stay as history. Only the bounded portion with source-to-order conversion evidence can pass BOQ quantity gate; the unresolved portion receives its own owner and next check.
Case 2: Linear trims are listed by piece
If linear trims are listed by piece, do not force the register to show a clean total. Split the line by unit, batch, package, zone or instruction revision until each outcome can be stated honestly. The quantity-basis controller reconciles the sum back to the original order and labels every provisional balance. This keeps a partial freeze decision from being misread as acceptance or instruction freeze of all related BOQ lines.
Case 3: Sets contain unequal components
Where sets contain unequal components, compare the unit-active condition with the instruction-authorized reference under the viewing, measuring or access conditions defined by the project-specific control. Record the limitation if a meaningful comparison cannot be made. The quantity-basis controller may request clarification, containment or a new check, but cannot invent a criterion. The final disposition must identify both authority and source-to-order conversion evidence.
Case 4: Supplier rounds without showing the pack basis
For supplier rounds without showing the pack basis, map the downstream consequence before choosing a remedy. Inspection, packing, document, loading and site-receiving files may each hold the old shipment identity or cargo count. The quantity-basis controller lists the affected records and prevents silent reuse of superseded information. The freeze decision is closed only after the physical BOQ line and every carrier-operative operational reference agree.
Case 5: A revised drawing changes the measured quantity
With a revised drawing changes the measured quantity, treat the shipping-instruction issuer proposal as an input rather than an instruction-authorized resolution. Preserve the original requirement, the proposed action and the quantity-basis controller's authorized response as separate submission lines. The quantity-basis controller verifies implementation on the stated quantity-basis boundary and records remaining exposure. A concession or schedule choice does not automatically prove technical conformity or satisfy BOQ quantity gate.
Related files and revision governance
For BOQ unit of measure reconciliation, keep the operating file connected to the material submittal register guide, cross-category finish schedule and mixed-material AQL plan. Plan sampling in the export packaging specification, state protection in the container-loading evidence plan, and link final placement to the supplier document requirements. Before an order, reconcile the HOMESEE sourcing services. Commercial context remains in project inquiry form, project-specific files go through the project references, and published BOQ normalization guide is a reference rather than a guaranteed outcome.
Issue the BOQ unit of measure reconciliation with a instruction revision, date, preparer and accountable approver. A change notice names the affected conversion lines and downstream files; it never relies on a newer filename alone. Messages and meetings may resolve questions, but their authorized answer returns to the carrier-operative register. Standards, photographs, declarations and sampling reports retain their own quantity-basis boundary: none becomes a universal compliance statement merely because it is submission-connected to the procurement file.
Practical review exercise
Test the unit reconciliation register with one real BOQ line and one deliberately difficult unit gap. Start at BOQ line and source revision, then trace source quantity and unit, conversion formula source and approved quantity or hold without verbal help from the preparer. Ask a second unit checker to perform 'normalize unit names and codes' and 'obtain the project-specific control approval' from the submission-connected carrier inputs. Next, simulate the case area is quoted by carton while keeping the original order and substantiation history visible. The unit checker should be able to identify the bounded freeze decision, the unresolved portion, the next owner and the exact source-to-order conversion evidence required before BOQ quantity gate. If two unit checkers reach different conclusions, improve the carrier input reference or instruction cell definition rather than adding an undocumented assumption. This exercise validates traceability and freeze decision clarity; it does not validate price, lead time, certification, factory capacity or destination compliance.
Buyer checklist for BOQ unit of measure reconciliation
Complete the checklist against the BOQ unit of measure reconciliation source set, not from memory:
- A stable buyer-controlled ID exists for every affected BOQ line or freeze decision.
- The controlling BOQ, drawing, schedule and specification revisions are named.
- shipping-instruction issuer references are mapped without replacing buyer identities.
- Proposed, submitted, instruction-authorized, rejected and superseded states are distinct.
- Every unit gap has an owner, due action and authorized freeze decision route.
- Physical samples and photographs have IDs, dates and stated limitations.
- cargo counts and units reconcile at the level needed for the instruction freeze freeze decision.
- Order, inspection, packing, loading and receiving impacts are mapped.
- Destination and contract requirements are assigned to qualified unit checkers.
- No price, MOQ, lead time, compliance or capability has been assumed.
- Superseded files are marked and cannot be mistaken for unit-active releases.
- The final record names preparer, approver, issue date and instruction revision.
Request a BOQ unit reconciliation review
To evaluate this control within a real sourcing package, use the project references and upload the BOQ, unit-active drawings, schedules, sample register and any existing BOQ unit of measure reconciliation. Include the destination, required-on-site context and the freeze decision dates your transport instruction has actually instruction-authorized. Mark unknown information as unknown rather than inserting an estimate.
HOMESEE can then prepare questions around the defined quantity-basis boundary and organize an RFQ discussion against those files. The response should be assessed against the project-specific control's technical, contractual and destination requirements. Sending information does not create a claim about price, MOQ, lead time, certification, production capacity or outcome.
